The Kansas City Chiefs running back had 14 touches for 153 total yards and a touchdown, and helped ease the load for the returning Matt Cassel(notes). His 80-yard run late in the fourth quarter – on the Chiefs’ first snap after the Rams pulled within 20-13 – locked the game up. Here’s a wicked stat: Charles has 1,961 rushing yards in his last 17 games. And he did that on only 297 carries. That’s a staggering average of 6.6 yards per carry.

A good bulk of extra carries would be short yardage situations that he doesn't get today, which would bring his per carry average down significantly. And there's no guarantee that he could consistently pull off big runs between 20-30 carries or get worn down by midseason.

Given that he's been banged up this season even in a platoon role, safe to say that putting him well over 300 carries is overkill.
